Imagine the feeling of flying on an airplane. Smooth sailing, clear skies, not a cloud in sight. It’s a relaxing ride that many take for work or recreational travel. Now imagine flying through clouds, with the turbulence of different intensities. While some sink and hold onto their seats, others view it like a rollercoaster ride with their adrenaline pumping. Christian Nairy and Jennifer Moore know a thing or two about that.
Nairy and Moore, two atmospheric science graduate students at the University of North Dakota, are part of NASA’s Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS). Their job is to operate probes on one of two aircraft used in the experiments. The P-3 aircraft that houses their airborne office flies directly into the snowstorms, allowing the instruments Nairy and Moore operate to measure snow particles and atmospheric properties within the storm clouds.
IMPACTS is the first comprehensive study of snowstorms in the Northeastern United States in 30 years. The campaign combines satellite data, ground-based radars, weather balloon launches, computer simulations, and airborne instruments to understand snowstorms. The goal is to develop greater comprehension of winter storm formation and development by using several instruments that examine the microphysical characteristics of snow particles at various temperatures and altitudes. The data collected during the multi-year IMPACTS campaign can help advance the future of snowstorm forecasting and predictions.
“If we understand the microphysics of the clouds, what we’re seeing, when we’re seeing them, and how we’re seeing them, it gives scientists in other disciplines a better understanding of what they’re studying,” said Nairy. The IMPACTS experiments will provide robust datasets about winter snowstorms for scientists to analyze and incorporate into their own research.
